This evidence class represents the Authenticode X.509v3 digital signature used to sign an assembly. The digital signature is passed as a System.Security.Cryptography.X509Certificates.X509Certificate argument to the Publisher constructor and is accessible after creation through the Certificate property.

The PublisherMembershipCondition class uses Publisher evidence during policy resolution to evaluate whether an assembly or application domain qualifies for membership of a CodeGroup.

Because the Publisher class implements the IIdentityPermissionFactory interface, an assembly or application domain with Publisher evidence will contain an appropriately configured System.Security.Permissions.PublisherIdentityPermission object in its grant set.
